So this is a story on how I unbricked my card, it may perhaps help someone in my situation.
To make a long story short! I bricked one of my RX580 8gb. I flashed 8 of them and the 9th, fails! So i know it was not the BIOS that was bad. Note! This model dose not have a BIOS switch.
So i began from the top and tired all the methods that have been described on the web...
* Flash from CMD
* And the most powerful of them all flashing from a booted dos USB.
* And the Super Man of flashing! BIOS bridge (Vlad did this one)
So i was thinking to my self! well, that is what you get for playing with fire, you stupid idiot!
Now you have a 300 dollar brick in your hands!
After crying like a little bitch.. I got in contact with this great you-tuber, called Vlad, a electronics wiz, that is into mining. I told him about my problem, and he offers to helped me. So i sent my GPU to him.
After a couple days, he responds. "Your BIOS chip was faulty.."
I was like "OMG, what?!?! I didn't even know that it was a thing."
Now, perhaps you are asking your self "How in the hell did that happen?". We don´t know.
it may have been faulty from the factory, or maybe it was some thing i did. We just do know.
